            This function is used to ask the strand to execute the given handler,
            but without allowing the strand to call the handler from inside this
            function.
          </p>
<p>
            The strand object guarantees that handlers posted or dispatched through
            the strand will not be executed concurrently. The strand's guarantee
            is in addition to the guarantee provided by the underlying <a class="link" href="../../io_context.html" title="io_context"><code class="computeroutput">io_context</code></a>.
            The <a class="link" href="../../io_context.html" title="io_context"><code class="computeroutput">io_context</code></a>
            guarantees that the handler will only be called in a thread in which
            the io_context's run member function is currently being invoked.
